Here is a list of the Libraries in Teensyduino: Obviously you are not limited to these libraries, many more general libraries can be used. AccelStepper Adafruit_NeoPixel Adafruit_nRF8001 Adafruit_STMPE610 Adafruit_VS1053 ADC AltSoftSerial Artnet...

Effectively you will be using the Teensyduino libs if you are using a Teensy. A lot of people use PlatformIO with Teensy but it is NOT a PJRC supported platform. Paul does a lot to help those people using PlatformIO with their problems but it is...

I would suggest using Teensyduino and the Arduino IDE so that all the libraries become available to you. Use VisualMicro and VisualStudio if you don't like the look and feel of the Arduino IDE.

If you break the connection and then put a Schottky diode across them you get the best of both worlds without having to re-solder.

Hi all, yes it's been a little bit. So I guess I lost my Teensy 4's, lol, so I'l order a 4 and 4.1 soon.

Let's start with the first serial port on pins 1&2, this is addressed as Serial1, so Serial1.begin(11520); works. Likewise for the second serial port on pins 7&8, this is addressed as Serial2 and Serial2.begin(11520); works. I am sure you get the...

The SDA lines may need to have pull up resistors added.

Could you explain what you mean by the above sentence. I think I know what you mean, but we have a large number of members who DO NOT have English as a first language and may not understand your sentence, especially the halts the Teensy inviting...

Hi, @duff it's so good to see you back.

I have some in the UK, if you are interested.

This should have the 9bit information you require.

Ditto on Windows 10.

Can't you buy the chips from Mouser then ship them to the PCB factory yourself?

Personally I would use OLED screens such as this. Square ones are available a little cheaper. They are driven by I2C which is slower than SPI, but I suspect that speed is not a priority as they will (I guess) not be changed very frequently...
